Dynamic Evaluation of Regional Sustainability Based on Improved Ecological Footprint Factors-A Case Study in Shaanxi Province
Ecological footprint is one of the important methods to assess regional sustainability
and current researches usually adopt nationwide equivalence factor and yield factor. This paper
taking Shaanxi Province as a case study
estimated independently the equilibrium factor and yield factor for each year
and improved the traditional evaluation methods. The results indicated that there were big difference between factors of Shaanxi Province and nationwide unified factor. From 1995 to 2011
Shaanxi Province was general unsustainable
and the ecological deficit and ecological pressure index changed between 0.1389~0.4978 hm2/cap and 1.1703~2.6137 respectively
and kept relatively stable. compared to the result calculated by the global unity factor
the data form the present study were smaller than normal study and more closely to regional reality. Being good for the negotiations on global ecological problems
it is necessary to establish a set of ecological footprint calculation factor and method conform to national condition and regional characteristics.
